Meversberg: Theraveda Buddhist monks eat once a day in the morning, and then fast for the rest of the day. I guess your method of eating is pretty close. I was sat next to a Bangladeshi Buddhist monk (yes, there are Buddhists in Bangladesh) on a flight and we got talking about Theraveda Buddhism, which I'm pretty interested in. He tried to give me his food, but I was stuffed, so he put all of it in his bowl so he could give it to someone when he got to Kolkata.
I wish everyone valued food that way...wasted food really bothers me because so much goes into its cultivation, especially in tropical areas, where more and more forest is being cleared for agricultural purposes. I try not to waste any food at all.
It is rather similar. I used to be a "three squares" guy but I always felt it was rather artificial. I turned into a grazer (six or so small meals) as I heard it was better but that was incorrect. After being introduced to the Primal/Paleo crowed, I adopted the single evening meal as my only meal. I'm not super strict, though, as I will do lunch with friends/fiance/coworker when it comes up.
I agree with food valuation. Especially here in the US, it's rare to find anyone who actually appreciates food. Some foods might get props, but it isn't real appreciation.
Some forms of food production are simultaneously food wasting, in my opinion. Iceberg lettuce has become my personal symbol of stupid agricultural decisions. That, and the entire corn-laiden midwest.
